In the Gash Bell volume rereleases (where the covers are redrawn by Raiku Makoto), there's a short series in each volumes called "Gash Cafe", where various Demons would talk and eat while their Partners serve them their favorites. During Kanchome, Folgore, Brago and Sherry's chapter, Brago is dared by Kanchome to sing a duet with Sherry, written and choreographed by Folgore, and they're actually pretty good.
